Experimental verification
For verifying the practical function of cement sewage disposal of the present invention and cyclic utilization system, the Behavior of Hardened Cement Paste block of certain university to the sewage disposal of the embodiment of the present invention 1 and cyclic utilization system precipitation-hardening has carried out core boring sampling, test its compression strength, meanwhile, sampling inspection has been carried out to the recycled water that the separate tank 25 by embodiment 1 precipitates the sewage former state after clarification and collecting-tank 28.
In this experiment, raw material are: the Portland cement of 42.5 grades, and particle diameter is the limestone gravel of 5-20mm, and modulus of fineness is thick river sand in 3.0, running water.It is the main source polluted that the cement granules carried in sewage is cleaned in cement mixing room, and after cement granules generation hydration reaction, in solution, leading ion has Ca

4 2-solution, contrast detects the concentration of these ions in sewage former state and recycled water, and the clean-up effect of the present invention to cement sewage can be described.In this experiment, single filter pond filler is the light haydite that 500mm is thick, and cascade filtration pond filler is the common natural fine sand that 500mm is thick.
The intensity test that the mortar of different designs match ratio and concrete sewage produce building block through precipitation-hardening the results are shown in Table 1:
The mortar of table 1 different designs match ratio and concrete sewage produce the intensity test result of building block through precipitation-hardening
。
From the result of table 1, the Behavior of Hardened Cement Paste of precipitation-hardening in sedimentation basin building blocks shaping mould, with the difference of former designing material match ratio, its compression strength is also had any different, according to existing national standards " small-sized ordinary concrete building block " GB/T8239-2014 to the requirement of building block compression strength, the compression strength of some mortar regenerative building block has reached MU15 level, can be used as the building block of load-carrying members, the compression strength of the concrete regenerative building block of some match ratio is the highest also reaches MU5.0 level, and the building block as non bearing structure is feasible.
Consider that filtering ponds filler may bring impact to relevant ions concentration, done contrast test simultaneously, namely carry out sample analysis to A-running water, the aqueous solution of B-running water after one-level, the filtration of cascade filtration pond, the clarified solution of C-separate tank, the aqueous solution of D-separate tank clarified solution after one-level, cascade filtration pond are filtered respectively, water quality detection result is as shown in table 2:
Table 2 water quality detection result
。
Shown by the testing result of table 2, running water is after one-level, cascade filtration pond are filtered, though ion concentration changes, but change is little, still meet the requirement of national drinking water standard GB5749-2006 to index of correlation, illustrate that material natural sand and light weight sand etc. are easy to get can use as the packing material in single filter pond, cascade filtration pond, obviously can filter out the solid particle in the clarified solution of separate tank.
The clarified solution indices of separate tank is higher than code requirement, especially extremely strong alkalescence is presented, if directly use can bring potential safety hazard, but its index of correlation reaches national drinking water standard substantially after single filter pond, cascade filtration pond double-filtration, can greening water or cleaning water be used as, water resource effectively can be utilized.
